we were playing safe and not allowed any container to have less than
65536 mappings. There are a couple of reasons to change it:
- it blocked libpod to work in an environment where
newuidmap/newgidmap are not available, or not configured.
- not allowed to use different partitions of subuids, where each user
has less than 65536 ids available.
Hopefully this change in containers/storage:
https://github.com/containers/storage/pull/303
will make error clearers if there are not enough IDs for the image
that is being used.

Add the ability to run the integration (ginkgo) suite using
the remote client.
Only the images_test.go file is run right now; all the rest are
isolated with a // +build !remotelinux. As more content is
developed for the remote client, we can unblock the files and
just block single tests as needed.

when testing rootless containers, it is more reliable to stop
a container with a zero timeout than kill a container. We made
this change in non-rootless tests as well. When IO or CPU are
taxed, it avoids a situation where the kill signal is sent but the
container has not been able to update its status when a subsequent
action occurs.

With rootless containers we cannot really restart an existing container
as we would need to join the mount namespace as well to be able to reuse
the storage, so ensure the container is stopped first.

The conmon exit command is running inside of a namespace where the
process is running with uid=0. When it launches again podman for the
cleanup, podman is not running in rootless mode as the uid=0.
Export some more env variables to tell podman we are in rootless
mode.

this pr allows the libpod integration suite to pass on the
ppc64le architecture. in some cases, I had to skip tests.
eventually, these tests need to be fixed so that they properly pass. of
note for this PR is:
* changed the ppc64le default container os to be overlay (over vfs) as vfs seems non-performant on ppc64le
* still run vfs for rootless operations
* some images names for ppc64le had to change because they don't exist.
* this should help getting our CI to run on the platform

Manage the case where the main process of the container creates and
joins a new user namespace.
In this case we want to join only the first child in the new
hierarchy, which is the user namespace that was used to create the
container.

We cannot re-exec into a new user namespace to gain privileges and
access an existing as the new namespace is not the owner of the
existing container.
"unshare" is used to join the user namespace of the target container.
The current implementation assumes that the main process of the
container didn't create a new user namespace.
Since in the setup phase we are not running with euid=0, we must skip
the setup for containers/storage.

Because our tests are getting so long, we want to be able to audit which tests are taking
the longest to complete. This may indicate a bad test, bad CI, bad code, etc and therefore
should be auditable.
Also, make speed improvements to tests by making sure we only unpack caches images that
actually get used.
